| 10 | * [structured clone algorithm](https://mdn.io/Structured_clone_algorithm) |
| 11 | * and supports cloning arrays, array buffers, booleans, date objects, maps, |
| 12 | * numbers, `Object` objects, regexes, sets, strings, symbols, and typed |
| 13 | * arrays. The own enumerable properties of `arguments` objects are cloned |
| 14 | * as plain objects. An empty object is returned for uncloneable values such |
| 15 | * as error objects, functions, DOM nodes, and WeakMaps. |
